IMPROVEMENT IN SEED-PLANTBRS.

TO ALL-WHOM IT. MAY CONCERN:

Be it known that I, H. C. FAIRCHILD, of Brooklyn, in the county of Susquehanna, and State of Pennsylvania, have invented anew and improved Gauge for Seed-Planters; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enablethose skilled in the art to make and use the same, reference being had to the accompanying drawings, forming'part of this specification. V

This invention relates to improvements made in a seed-planter for which LettersPatent of the United States were gauge that it can be set on the corn-hopper from the outside, as will be hereinafter described.

Figure 1 represents a vertical longitudinal view of a hand-planter, partly in section, in order to show to better advantage the interior arrangement.

Figure the gauge and the manner of its adjustment.

Similar letters of reference indicate corresponding'parts.

A represents the cylinder; B is the plunger; C is the mouth-piece; using the planter, is partially rotated by the p ing this gauge the Orifice E is enlarged or diminished in size, and the quantity of seed which'is delivered is determined thereby. The gauge or slide D is operated by a screw, marked a, which is fixed as regards its longitudinal motion, but which may be rotated by a screw-driver. This screw passes through and engages with an arm, a, which forms a nut for it. This arm is attached to the slide D, soit-hat when the screw is turned cr fevolved the result is that the arm 0, with the slide or gauge D, is moved back and forth over the orifice E, thus diminishing or increasing the quantity of seed delivered, as may be desired.

In my patented planter (bcfore'alluded to) it is extremely difiicult to operate or change the gauge. By my present arrangement it is done with the greatestfacility. is a hole through the cylinderfwhich gives access to the screw a, and with a common screw-driver the position of the gauge can be altered in a moments time. f, fig. 1, is the aperture through which. the seed passes into the mouth 0. a

In operating with the planter the plunger-rodB is artially rotated by the hand. As the mouth is inserted D represents the gauge, which, when granted me in 1860; and the invention consists in such a construction and arrangement of the- 2 is a cross or horizontal .section of thesame through the line :0 :v, on an enlarged scale, showing hinger between two stationary disks in the cylinder. By adjust-- into the earth the plant-er is carried and supported by the other hand with the curved handle, as seen in redlines in fig. 1.

Having thus described my invention, 1 claim as new, and desire to secure by Letters Patent 1. The slide D, operated from the outside bythe screw a and the arm a, substantially as described.

2. The hole (1 through thc'cylinder, substantially as and for the pnrposes herein set forth I H. O. FAIRGHILD.
